Abstract
Acute pancreatitis (AP) is an inflammatory process of the pancreas, with variable involvement of peri-pancreatic tissues and remote organ systems. In 80% of the cases the disease is mild, with interstitial oedema, and leads to recovery within days or weeks.
Severe forms, characterized by local or systemic complications, which may be demanding, associated with severe morbidity or even death, in up to 15-20%.
The revised Atlanta classification includes new definitions that more accurately describe the various types of collections encountered: APFC, pseudocyst, ANC, and WON. The important distinctions for classifying collections correctly are the time course (≤6 weeks or >6 weeks from onset of pain) and the presence or absence of necrosis at imaging.
CT is the Gold standard noninvasive imaging, Findings included:
The Balthazar score, It divides patients into five classes (A-E), according to the anatomical changes of the pancreatic and peri-pancreatic tissues.
The CT severity index (CTSI) is based on findings from a CT scan with intravenous contrast to assess the severity of acute pancreatitis.
A thick-walled, rounded, and fluid-filled mass adjacent to the pancreas in case of pseudo pancreatic cyst.
Internal drainage of pancreatic pseudocysts and WON can be accomplished by traditional open or minimally invasive laparoscopic or endoscopic approaches.
The aim of this retrospective study is to evaluate the different treatment modalities for acute pancreatitis with fluid collections and sequels (PP, ANC and WOPN) as regard to morbidity, mortality, hospital stay, successful rate.
This retrospective study included 128 patients complaining of acute pancreatitis with fluid collections and sequels that needed intervention (45 patients with free collection, 32 patients with PP, 23 patients with WON, and 28 patients with NP). Forty-five patients with acute edematous pancreatitis with free collection were managed conservatively successfully.
